Brushless motor constat moderatorem ad tempus motricium tempus coil electricity ad producendum rotating magneticam agri motor rotor gyrari rotating magnetica agro. When the hall element in the N pole and s pole is different when the potential, the center hall element from a N pole through a magnetic boundary of magnetic steel enters another s pole, just at the moment through a magnetic boundary, hall element instead of potential output, with the potential to control circuit of the controller, the brushless motor flux of coil current direction change, so as to achieve the purpose of motor electronic commutation, when reversing the center line of the Hall elementum et coil reversing positio centrum linea in ore sit accidit.
